Problems with Internet Explorer after Windows Updates

After the latest Windows update last week, login via Internet Explorer is no longer possible.
An empty home page without login fields is loaded.
Has anyone here had the same experience?

Running NC19 on Ubuntu 18.04 server.

Not sure if it’s related but protocols show following message regulary:
Deprecated event type for {"[object] (OCP\SabrePluginEvent)":{"*statusCode":200,"*message":"","*server":{"[object] (OCA\DAV\Connector\Sabre\Server)":{"tree":"[object] (OCA\DAV\Connector\Sabre\ObjectTree)","*baseUri":"/remote.php/webdav/","httpResponse":"[object] (Sabre\HTTP\Response)","httpRequest":"[object] (Sabre\HTTP\Request)","sapi":"[object] (Sabre\HTTP\Sapi)","*plugins":[],"transactionType":null,"protectedProperties":{"...":"Over 20 items, aborting normalization"},"debugExceptions":false,"resourceTypeMapping":[],"enablePropfindDepthInfinity":true,"xml":"[object] (Sabre\DAV\Xml\Service)","*listeners":{"...":"Over 20 items, aborting normalization"},"*wildcardListeners":[],"*listenerIndex":[],"*logger":null}},"Symfony\Contracts\EventDispatcher\EventpropagationStopped":false}}: null

Really Internet Explorer not Microsoft Edge with Chromium? Please post a screenshot.
Is Internet Explorer supported?

We are still transitioning to Windows 10.
Actually works with Edge Browser.
But even on a Win10 machine Internet Explorer is still available…

Ok it tested it with Windows 10 and Internet Explorer.

I tested Nextcloud 18 and it works.
I tested Nextcloud 19 and it does not work.

Same error like you. Sorry.
Use better and newer browsers. Internet Explorer is dead.
Perhaps you are the last user of Internet Exlorer.
Read the problem today first time.

With a lot of hope it is only a javascript problem.
Perhaps you can search in this way.

All other users with Internet Explorer:
Do not upgrade to Nextcloud 19.
